What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Traditional dynamic random access memory (DRAM) technology faces grand challenges in power consumption due to the constant data refresh and in density due to the physical limit for dimension scaling. Recently, two-transistor zero-capacitor (2T0C) DRAM based on amorphous indium gallium zinc oxide (IGZO) exhibits long data retention owing to its extremely low off-state leakage current. Furthermore, the low thermal budget of the IGZO channel enables the monolithic three-dimensional (3D) stacking for higher bit density beyond the planar scaling limit. However, the demonstration of 3D stacking for IGZO has been limited to 2T0C DRAM single cell. In this work, an 8 by 8 3D stacked IGZO 2T0C DRAM array was designed and manufactured with optimized electrical characteristics, exhibiting 3-bit storage with over 100-second retention time. Furthermore, a neural network model has been demonstrated to achieve an accuracy of 94.95% in image recognition, providing for promising pathway toward computing in memory to overcome the "memory wall."
